  A plano concave cylindrical lens   is used to condense light in one axis.  A positive plano cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, please contact Ecoptik   (also known as BRD Optical).   Plano Convex Cylindrical Lens Descriptions The Plano spherical lens acts symmetrically on the incident light in both directions, while the convex cylindrical lens   acts in only one direction on the incident light.  A typical application is to shape a deformed beam with a pair of plano-convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to...

  Ecoptik  (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations   Descripion Of Positive&Negative Meniscus Lens Ecoptik  (also known as BRD Optical) provides meniscus lenses  in both positive and negative focal lengths.  On the aspect of shape, it can be divided into convex meniscus lens and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens.   Positive Meniscus Lens A positive meniscus lens consists of two curved surfaces with similar radii of curvature and has a positive focal length. Positive meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, e...

Aspheric lenses can improve image quality and correct imaging problems usually associated with spherical lenses. The original work and function of the aspheric lens are mainly reflected in the following aspects:   1. The spherical aberration of spherical lenses In a spherical lens, light is focused at different distances (depending on where it enters relative to the edge of the lens), which can cause blur and peripheral distortion. This phenomenon is called spherical aberration.   Aspheric lenses advantages : aspherical lenses can reduce or eliminate this problem due to its unique design (with a shallower surface curvature angle). When light enters the aspheric lens, whether it enters or not, it will be focused to a point, resulting in a clearer and sharper image.   2. Distortion of spherical lens When spherical lenses zoom in or zoom out an image, they will distort and bend the lines viewed through them. Since the edge power of the aspheric lens is low, the risk of pincu...

Optical Products in Laser Optical System   Lasers have very good coherence, directivity and high concentration of energy.   The advent of the laser means that the optical element is no longer limited to the observation and recording of the original shape of the image, but the image is processed and recorded by the transformation of the time and space spectrum. In addition, in optical measurement, the use of laser precision is also higher than before.   Because the laser itself has very good coherence, when the material itself has defects, dust or bubbles, stripes, etc., it will be easy to produce noise, because the material is very strict in the selection, and in the processing process, the processing precision of the components to be very high requirements. Especially for the opposite type. Usually, it needs to be at least λ/10-λ /20 or so.   Ecoptik focuses on high precision custom machining. we have a wealth of experience in laser products.   For example, ...
